When the USB is plugged in, the Smart Chip senses the connected device and sends it the most power to charge as fast as possible.

Once your device is fully charged (100%), the Extō USB port shuts off to protect the battery from overcharge (a primary cause for battery life reduction). This preserves battery capacity and extends device life.

You'll never have to search for a USB adapter with the Extō USB and you'll never want to hide it, either.

The Extōs also converts to a table lamp using a direct plug bulb socket (not included), the Extō is the only modular power source with internal tamper resistant barriers protecting the electric current from little objects, helping prevent shock.
